How to determine whether a point is in the eastern hemisphere, the western hemisphere, the southern hemisphere or the northern hemisphere?
The northern and southern hemispheres are easy to say, that is, looking at the equator, the northern hemisphere is north of the equator and the southern hemisphere is south of the equator;
The eastern and western hemispheres are divided by 20 W and160 E. The eastern hemisphere is east of 20 and the western hemisphere is east of160 (China is the best example, and we are an "oriental" country).
